We know who are the first Bitcoin billionaires. They were made by Bitcoin itself because this digital currency hit $11,826.76 a coin on Sunday. Bitcoin has attracted interest from both ordinary investors and institutions. They are being drawn in by the promise of big gains.

The two former Olympic rowers twins Cameron and Tyler Winklevoss,36, disclosed in 2013 that they owned $11 million worth of bitcoin. Now, their investment is worth over $1 billion. They are long-time bitcoin addicted and are also investors in the crypto exchange Gemini. Cameron and Tyler Winklevoss, born in Southampton, New York, are known for co-founding HarvardConnection, a social networking website (later renamed ConnectU) along with Harvard University classmate Divya Narendra.

In 2004, the Winklevoss brothers sued Facebook founder Mark Zuckerberg, claiming he stole their ConnectU idea to create the popular social networking site, and ultimately received $65 million. The Winklevoss twins own one of the largest portfolios of Bitcoin in the world. When the Winklevoss’s invested in Bitcoins, the currency was trading at just $120. The digital currency has surged almost 10,000 per cent They later argued it was “better than gold”. The brothers have not sold a single one of their Bitcoins, watching them accruing value. As the most widely traded “cryptocurrency”, bitcoin exists only as strings of computer code but concern over its extreme volatility has not slowed its rapid rise.
